known methods reported on the following pages. About the Benchmark: TPC‐C and tpcc‐mysql TPC‐C is an OLTP industry standard benchmark developed and maintained by the Transaction Processing Performance read‐only and update‐intensive transactions that represent complex OLTP application activities. The benchmark implements five types of transactions (new order, payment, delivery, order status and stock level) traditionally I/O bound, thereby increasing throughput by orders of magnitude, measured with tpcc‐mysql benchmark. 3. Optimizing MySQL Server and Percona Server for SSDs We observed that the NVMe SSDs performed

pressure decreased after HBASE-21879, while it’s effect is not good as the disabled blockCache benchmark case now. Because as the cache hit ratio increased, we will have much less request to read the BlockCache: ~ 100% CacheHitRatio To ensure the HBASE-21879 won’t make high overhead, we made a benchmark in a small test data set which will have a 100% cacheHitRatio.
